Hello cribbj, I've done what you told me to do. Thank you!
Take care.

Steve, mine was a leaking Schrader valve at the test port on the high pressure line. Once that was replaced, and the system evacuated & recharged, it's been good since. We're also suspecting the compressor may have a leaking front seal, so that may go in for an overhaul soon. The independent Ferrari specialist I deal with has located a local facility that overhauls compressors for around $300 vs buying new for ~$1600-$1800, so we'll probably give them a try.

were you ever able to determine your a/c problem-i think i have something similar in my 01 550-i suspect an air blending issue. thanks, steve, sme@eisnerfowler.com
